Project Details:
In two pig farms in three subsequent nursery periods animal health data, daily weight gain and
treatments will be compared between two identical piglet rearing compartments. In one
compartment the drinking water pipes will be cleaned prior to arrival of piglets by an innovative
cleaning process. The cleaning process combines mechanical cleaning forces using a mobile
flushing device equipped with a constant pressure system, with a new chemical cleaning concept.
The cleaning substance is based on the synergistic interaction of vitamins, organic acids, metal
ions and detergents, each of which attacking different target structures of pathogens. The
process resulted in a strong antimicrobial efficacy and in destruction of extracellular nucleic acids
(e.g. genes coding for resistance against antimicrobials). The effectiveness of the cleaning
process will be verified by chemical and microbiological examination of water pipe deposits prior
to and after cleaning. The cost-effectiveness of the process will be evaluated by performance
data, expenditure of time and material costs.

The aim of this project is to implement a simple and effective process for water treatment in aquaculture and to reduce harmful emissions from fish farms. A denitrification process is used for this purpose, which is coupled with a membrane unit in order to eliminate solids such as bacteria, parasites and other microparticles and to increase the biomass concentration in the denitrification reactor.

Tagging wild animals is important to investigate their behaviour and habitat use. The project "Realising a game changer in tagging wild animals; stress-free instrumentation" is part of the funding initiative ‚Experiment‘ of the Volkswagen Foundation. Its goal is to achieve a less stressful tagging experience for wild animals. To this end, so-called self-affixing smart tags are under development. For this, animals do not need to be caught and immobilized, but they can nevertheless be equipped with new hi-tech devices that inform researchers about their habits. Smart tags are undergoing testing in, and customisation for, several different species. The goal is to reduce any stress experienced by animals while being outfitted with transmitters to make this process more animal-friendly. Another advantage is that data recorded after tagging are immediately usable, rather than researchers having to discard initial data because the animal is behaving aberrantly following capture. Indeed, after attaching the types of transmitters used to date, animals usually display abnormal behaviour, which can lead to considerable deviations in measured data and even to the tagged animal leaving its usual habitat. Animal tagging is employed in many research projects worldwide. The collected data provide information about how animals live, their use of space, energy expenditure, behaviour, and even emotional states. Thus, they provide important information for protection and management. Indeed, such is the power of the approach that it has progressed to a distinct discipline called biologging.

Project Details:
In addition to antimicrobial molecules, nitrate and nitrite ions are also produced during the generation of PAW. PAW could thus be suitable as a basis of brines for curing meat products. On the one hand, the addition of classical nitrite curing salt could be minimized, on the other hand, the antimicrobial molecules contained in the PAW could have positive effects on the shelf life of the products. As part of the project, a novel production process of wet-cured meat products using PAW will be established and possible positive but also negative effects on the product will be determined.

This research project will compare the meat quality of buffalo and conventionally raised cattle. Using different storage and cooking methods, the widespread perception of tough and difficult-to-prepare buffalo meat will be scientifically analyzed. In addition to the comparative characterization of basic meat properties such as pH and conductivity,
water holding capacity, nutritional values, collagen content and texture parameters, microbiological investigations and, in particular, a sensory evaluation of the two meat species will be carried out.

We applied for an follow-up financing in order to increase the reach, the attractiveness as well as the functionaliy of the platform. Due to corona this was not possible to a sufficient extent within the originally planned projekt period. The following optimizations are now planned for the top-up phase:
Target group expansion to include interested non-scientists.
Networking of 3R-SMART with established online portals of external partners.
Integration of an area with Open-Educational-Resources.
Integration of a collection of contributions to 3R centers.
Integration of interactive elements into existing contributions.

Project Details:
Harbour porpoises are representatives of the top predators from the group of mammals in the North Sea and Wadden Sea. With the amendment of the National Park Act in 1999, part of the National Park was explicitly dedicated to harbour porpoise protection, as a high density of mother-calf pairs was found there. As part of the reorganisation of the Federal-and State Marine Programme (BLMP), a programme for joint monitoring of marine mammals was agreed in January 2011, which meets the requirements of monitoring according to the relevant European guidelines and international conventions. In this programme, the Schleswig-Holstein National Park Administration (NPV) in the Schleswig-Holstein State Agency for Coastal Protection, National Parks and Marine Conservation (LKN) has the task of organising, implementing and financing the acoustic monitoring of harbour porpoises. The acoustic surveys for the NPV are carried out by the Institute for Terrestrial and Aquatic Wildlife Research (ITAW) as part of the joint marine mammal monitoring under the BLMP. For this purpose, measuring stations are operated at five specified sites in the Schleswig-Holstein Wadden Sea (Lister Tief, Meldorfer Bucht, Rochelsteert, Westerland and Elbe river). The monitoring stations are equipped with click detectors (Cetacean-Porpoise Detectors, C-PODs), which record the echolocation activity of harbour porpoises. The C-PODs are maintained and data downloaded on a regular basis. The data obtained are evaluated for optimising the acoustic monitoring as well as necessary extensions for a permanent operation of the measuring stations.

Results:

For over eleven years, porpoises have been regularly detected at all five measuring stations in the Schleswig-Holstein Wadden Sea, with significant spatial and seasonal differences in detection rates. The highest detection rates were recorded at the Westerland, Meldorfer Bucht, and Elbe river stations, while Lister Tief consistently showed the lowest values. All stations showed a seasonal maximum in spring, with the Rochelsteert and Außenelbe stations showing a pronounced maximum in autumn. This maximum coincides with the mating season and indicates that these regions are used more intensively during the reproductive phase. In the Elbe estuary, the low detections in spring suggest that porpoises follow their prey fish into the rivers and reoccur in the estuary in autumn. In addition to the seasonal patterns, there were also slight area-dependent patterns related to tides and time of day. The long-term data confirms the importance of the Wadden Sea as a key habitat for porpoises and enables robust trend analyses, which necessitate continued monitoring.

Ab dem 28.01.2022 tritt das neue Tierarzneimittelgesetz in Kraft, sodass es ab diesem Zeitpunkt immer wichtiger wird, Hochleistungstiere durch optimierte Ernährung gesund zu erhalten. Ziel dieses Projektes ist eine Verbesserung der Eutergesundheit und damit einhergehend der Milchqualität durch den Einsatz von Pflanzenkohle, die mit Vitamin E angereichert wird. Zunächst soll in vitro der Effekt der Pflanzenkohle auf die Fermentation im künstlichen Pansen (RUSITEC) untersucht werden. Basierend auf den Ergebnissen der in-vitro-Studie wird anschließend die Pflanzenkohle bei laktierenden Milchkühen über das Milchleistungsfutter dosiert.
